In detail, the present invention relates to

BACKGROUND ART

In 1977, mitocondorial benzogeazepin receptor (hereafter, it is abbreviated as MBR.) was identified as a receptor that is different from a benzodiazepine binding site in GABA_(A) receptor to which benzodiazepines bind (“Science 198, 849-851, 1977”; “Proc. Natl. Acad. Sci., 89, 3805-3809, 1977”), it has been reported to take part in steroid synthesis, the differentiation and proliferation of cell, and the immune function modulate, etc. though a physiological function is not necessarily clarified. In peripheral tissue, there are MBR in immune system cells such as red blood cell, platelet, monocyte, and macrophages beside adrenal cortex, heart, smooth muscle, kidney, lungs, testis, and in plexus chorioideus, pineal body, olfactory bulb, cerebral cortex, and hippocampus, etc. of central nervous system. Expressing cells in central nervous system has been known to be glia cells mainly, it may be used as a marker of gliosis so that the expression may increase along with the neurodegenerative diseases such as alzheimer's disease, cerebral ischemia, multiple sclerosis, and huntington's disease, etc.

It has been reported that when exposed to chronic stressors, morphologic changes like neuronal death in CA3 field and the shrinkage of dendrite, etc. is admitted in hippocampus and that the number of glial fibrillary acidic protein positive cells increases (Stress, 3, 275-284, 2000). It has been suggested that the activation of MBR could happen in glia cells at stress.

There are MBR in mitochondrial outer membrane, which transports cholesterol from intracellular to the internal membrane of mitochondria that is the active site of P-450 scc. Steroid synthesized in encephalon is called as neurosteroid, cholesterol, which is the steroid precursor, is converted into pregnenolone with side chain cleavage enzyme P-450 scc in the first stage of steroidogenesis system. However, it has been presented that this transport process rather than in the metabolism by P-450 scc is a limiting in the steroid production system. It has been thought that the content of neurosteroid in encephalon can be adjusted if the function of MBR can be adjusted. Actually, it has been reported that a diazepam binding inhibitory protein (diazepam binding inhibitor; hereafter, it might be abbreviated as DBI.) identified as an endogenous ligand of MBR and a benzodiazepine binding site in GABA_(A) receptor promoted the pregnenolone synthesis at mitochondrial fraction from rat brain and glioma cells.

It has been presented that DBI content increases in hippocampus by load sound stressor to rat and DBI density in cerebrospinal fluid of depression patients rises, and is expected that the amount of neurosteroid production could increase at stress. It is reported that the contents of various neurosteroids increase in encephalon by load stressors such as forced swimming, foot shock, expose of carbon dioxide, and restriction as experimental results that proves this.

Neurosteroid adjusts the function of various receptors and ion channels positively or negatively according to the type. For example, though pregnenolone sulfate and dehydroepiandrosterone sulfate control the function of GABA_(A) receptor, progesterone activats that. And, though pregnenolone sulfate controls functions of AMPA/kainic acid-type glutamate receptor, glycine receptor, and voltage-dependent calcium channel, on the other hand, activates the function of NMDA-type glutamate receptor. Progesterone controls the function of acetylcholine receptor together with glycine receptor. In addition, progesterone is oppositely controled though dehydroepiandrosterone sulfate activates the function of σ receptor. It has been thought that the change of activity of nervous system, immune system, and endocrine system variously adjusted with these nervous systems and the development of diseases related to various stresses could be caused to the collapse of balance between an excitatory signal transmission system and an inhibitory one by the shift of the amount of neurosteroid in encephalon at stress. Considering reports that pregnenolone sulfate reinforces NMDA induced cell death of culture hippocampal neurones and causes late cell death with DNA fragmentation in neural retina cells, the possibility that pregnenolone sulfate also takes part in the degeneration of hippocampus CA3 field at stress partially at least is suggested.

As mentioned above, the inhibition of increase of neurosteroid production via anomalously activated MBR by stressor load and the recovery of balance between the excitatory signal transmission system and the inhibitory one to be normal are effective for the treatment of the disease related to stress. Therefor, it is expected that MBR antagonists could be extremely useful for prevention and treatment of these diseases.

As the result, the compounds of the present invention have actions that recover working of nerve, immunity, and endocrine system by controlling the abnormal increase of steroid production caused by stressors and recoverring the balance of excitable or inhibitory signal transduction changed by neurosteroids.

Under load of stressors to organism, amounts of various neurosteroid as the metabolites increase by increasing production of pregnenolone via MBR in mitochondria of glia cells. Since neurosteroids positively or negatively modulates the function of each kind of various receptors and ion channels, the change of activity of nervous, immune, and endocrine system variously adjusted by these nervous systems and diseases related to various stresses are caused by the collapse of balance of excitable or inhibitory signal transduction. The medicine of the present invention recovers the function of nerve, immunity, and endocrine system, which is accompanied by the control of anomalous increasing production of neurosteroid by the activation of MBR.

The present compound, which can bind to MBR, acts as a competitive antagonist against MBR agonist to increase neurosteroid production by binding to this receptor [for example, FGIN 2-[2-(4-fluorophenyl)-1H-indol-3-yl]-N,N-dihexylacetamide:“J. Pharmaco. Exp. Ther., 262, 971-978, 1992”]. It is thought that the present compound demonstrates an anti-stress action by acting as an antagonist against MBR and antagonizing the increasing activity of steroid production caused by endogenous MBR ligands.

Therefore, the present compound is characterized in (a) the action that controls steroid production by MBR agonists, and (b) based on the depression of steroid production, the expression of the anti-stress action by decreasing neurosteroid followed to return the balance of the excitable or inhibitory signal transduction to be normal. The identification means of the above feature has been described on this specification.

The present compound having MBR antagonism can prevent and/or treatment for exacerbative and recrudescent diseases caused by stressors by returning the balance of the excitable or inhibitory signal transduction to normal by suppression of neurosteroid production and recoverring the function of nerve, immunity, and endocrine system. Identification means of action as MBR antagonist and anti-stress action of MBR antagonist are concretely explained in experiment examples on this specification.

It was proved by the following experiments that the present compound represented by formula (I) has MBR antagonistic activity and that it is effective for the diseases caused by stress.

In the following experimental examples, PK11195 is MBR ligand [1-(2-chlorophenyl)-N-methyl-N-(1-methylpropyl)-3-isoquinoli necarboxamide: “Eur. J. Pharmacol., 119, 153-167, 1985”], FGIN1-27 is MBR agonist [2-[2-(4-fluorophenyl)-1H-indol-3-yl]-N,N-dihexylacetamide:“J. Pharmacol. Exp. Ther., 262, 971-978, 1992”].

Experiment 1: Receptor Binding

The affinity of the compound to MBR was determined using rat brain membrane preparation. After male wistar rats were decapitated followed to remove the whole brain, cerebellums were removed. They were homogenized in ice-cold 50 mmo/L Tris-HCl buffer (pH7.4) and the homogenates were centrifuged at 12,000 g for 20 min (4° C.), and then their supernatants were discarded. The residual pellets were washed in the same buffer. The pellets resuspended in 50 mmo/L Tris-HCl buffer (pH7.4) and adjusted to about 1 mg/mL were used as rat brain membrane preparations for binding assay. The binding assay was experimented using [3H]PK11195 as a selective MBR ligand.

To determine the amount of total binding in saturation binding study, membrane preparations, various concentrations of [³H]PK11195, final concentraion: 0.5 vol % dimethylsulfoxide (DMSO) and 50 mmo/L Tris-HCl buffer (pH7.4) (total volume of 200 μL) were incubated for 1 hour at room temperature. To determine the amount of non-specific binding, 20 μmol/L of PK11195 was added in place of DMSO were incubated for 1 hour. The mixture rapidly was filtrated on GF/B filter soaked with 0.3% polyethyleneimine using cell harvester, which was washed twice with 50 mmo/L Tris-HCl buffer (pH7.4). After drying, the radioactivity on the filer was measured by liquid scintillation counter. The data were analyzed using analysis soft KELL (Ver. 6, BIOSOFT). The dissociation constant (K_(D) value) was determined by using scatchard analyses.

To determine the amount of total binding in competition binding study, membrane preparation, final concentraion: 1 nmol/L of [³H]PK11195, final concentraion: 0.5 vol % of DMSO and 50 mmol/L Tris-HCl buffer (pH7.4) (the total volume of 200 μL) were incubated for 1 hour at room temperature. To determine the amount of non-specific binding, 20 μmol/L of PK11195 was added in place of DMSO, on the other hand, to determine the affinity of the invention, final concentraion: 10 pmol/L to 1 μmol/L of the compound dissolved in DMSO was incubated in place of DMSO. The reaction was terminated as above described 1 hour later, then radioactivity on the filer was measured by liquid scintillation counter. The concentration of the compound required to reduce [³H]PK11195 binding to 50% of the amount of specific binding of [³H]PK11195 (IC₅₀ value) were derived from the data obtained. The inhibitory constant (K_(i) value) was derived according to the equation of Cheng & Prusoff (Biochem. Pharmacol., 22, 3099-3108, 1973). The K_(i) values of the compounds of the present invention are shown in table 6. These results clearly indicate that these compounds have high affinity to MBR.

TABLE 6 Example Num Ki (nM)  7 (5) 5.5  7 (18) 0.09 14 32 Experiment 2: Determination of Pregnenolone in Rat Adrenocortical Mitochondria

The steroid productivity of the present compound was evaluated using rat adrenocortical mitochondria.

After intraperitoneal administration of 20 mg/mL (1 mL) cycloheximide, 10 IU/mL (0.3 mL) adrenocorticotropic hormone (ACTH) was intraperitoneally administered to Male SD rats 5 minutes later. Then, rats were sacrificed by cervical dislocation 20 minutes later and bilateral adrenal cortexes were extirpated at once. The extirpated adrenal cortexes were homogenized in buffer A (50 mmol/L Tris-HCl, 250 mmol/L Succrose) followed to be centrifuged at 2,000 g for 3 min (4° C.). The supernatant was centrifuged at 12,500 g for 10 min (4° C.). The residual pellet was resuspended in buffer A followed to be centrifuged at 12,500 g for 10 min (4° C.). The pellet was washed again and finally suspended in buffer B (250 mmol/L Succrose, 10 mmol/L potassium phosphate buffer, 15 mmol/L triethanolamine, 20 mmol/L potassium chloride, 5 mmol/L magnesium chloride, 10 μmol/L trilostane, 10 μmol/L SU10603) for experiments. Malate (150 mmol/L), β-NADP⁺ (5 mmol/L) and the compound in a total volume of 25 μL were incubated for 5 min at 37° C. Then, 225 μL of mitochondrial membrane fraction from rat adrenal cortexes in buffer B preincubated for 5 min at 37° C. was added, then further incubated for 10 min at 37° C. to produce pregnenolone (final concentration of the compound: 1 μmol/L). The reaction was terminated by addition of ethanol (1 mL) and the organic phase extracted with n-hexane (1.25 mL) was collected and evaporated. The residual was dissolved in buffer C (0.1% gelatin in phosphate buffered saline) followed to be centrifuged at 12,000 g for 5 min, and the supernatant was collected as a sample for determination. [³H]Pregnenolone (10,000 cpm, 100 μL), pregnenolone antibody (ICN Biomedicals Inc, 100 μL) and sample (100 μL) were mixed and incubated overnight at 4° C. Then, dextran/charcoal (200 μL) was added to the mixture, which was mixed well and was kept on ice for 10 min, and was centrifuged at 1,000 g for 10 min (4° C.). The radioactivity of the supernatant was measured by liquid scintillation counter. The pregnenolone content in the sample was calculated from standard curve. Though pregnenolone content in FGIN1-27 treated group was higher than that in DMSO treated group, in the present compound treated group was as same as that in DMSO treated group. These results indicated that the present compound did not influence pregnenolone production in DMSO treatment group though FGIN1-27 is a MBR agonist which increase pregnenolone production more than in DMSO treated group.

Experiment 3: Measurement of MBR Antagonist Activity in Rat Adrenocortical Mitochondria

The effects of the compounds of the present invention on 1 nmol/L of FGIN1-27-stimulated pregnenolone production in an experiment according to the method described in Example 2 indicated that the compounds of the present invention antagonizes to steroid-productive action of MBR agonist.

Experiment 4: Effect of the Present Compound on Increase in Pregnenolone Production in the Brain Under Stress.

Psychological stress was loaded to male Wistar rats (Brain Res., 641, 21-28, 1994). Water was saved up to the depth of about 10 cm in a container where the platform had been installed at the center. The vehicle or the compound was orally administered to the rats in the stressed group though neither administering nor stressor were loaded to the rats in the non-treated group. The stressor was loaded to the rat put on the platform 30 minutes later, and the bilateral hippocampus were removed and weighed after microwave (output: about 6.5 kW, exposure time: 0.96 s) was irradiated with a microwave applicator(Muromachi Kikai Co., Ltd.) 1 hour later from stress loading. Internal standard substance (D4-pregnenolone 20 ng), water (1 ml), and diethyl ether/n-hexane (3 ml) (9:1) were added to the crushed hippocampus and stirred. After being crushed by supersonic wave and stirred again, the organic layer obtained by centrifugal for 5 minutes at 3,000 rpm was transferred to a new tube with pasteur pipet. The water phase were extracted with diethylether/n-hexane (9:1) again, then the organic phase were added to the preserved one. The residual dried under reduced pressure were dissolved in 150 μL of H₂O/acetonitrile (1:9), and then was measured by LC-MS. The measurement conditions are as follows.

-   LC: Hewlett Packard series 1100; -   Column: Inertsil ODS-3, 3 μm, 2.19^(φ)×100 mm; -   Temperature: room temp.; -   Mobile phase: 5 mmol/L CH₃CO₂NH₄/MeCN (10:90); -   Flow rate: 0.2 mL/min; -   Injection vol.: 40 μL. -   MS: Quattoro II (Micromass); -   Ionization mode: Atmosphere Pressure Chemical Ionization (APcl); -   positive; Corona: 3.4 kV; -   Sheath gas: N₂ (50 L/hr); -   Source temperature: 180° C.; -   Probe temperature: 550° C.; -   Detection: Pregnenolone: m/z 317.2 (cone: 10 V); -   D₄-pregnenolone:m/z 321.2 (cone: 10 V).

Pregnenolone content in hippocampus of vehicle-treated group significantly increased compared with that in non-stressed group. On the other hand, the increase of pregnenolone content was significantly inhibited in the group to which 3-30 mg/kg of the present compound was orally administered. These results indicate that the compounds of the present invention inhibit increase of pregnenolone content in hippocampus on stress.

Experiment 5: Evaluation of Anti-Stress Effects of MBR Antagonists.

Psychological stress was loaded to male Wistar rats (Brain Res., 641, 21-28, 1994). Water was saved up to the depth of about 10 cm in a container where the platform had been installed at the center. A stressor load was begun 30 minutes after the vehicle or the present invention compound was orally administered. The number of defecation was counted (10 per each group) 1 hour later. Rats without administeration and the load of stressor did not rarely defecated for 1 hour. On the other hand, remarkable defecation was admitted in media treatment group which the stressor had been loaded. However, it turned out that the number of defecation in the present compound treated group was significantly suppressed more than the vehicle one. These results clearly indicate that MBR antagonists have anti-stress effects.
